Application filed September 23, 1922. Serial No. 590,063.

To all whlom it may concern:

Be it known that I, STERLING H. CAMP- BELL, a citizen of the UnitedStates of America, residing at the city of St. Louis, State of Missouri,United States of America, have invented a certain new and useful CouplerRelease Rigging, of which the following is such a full, clear, and exactdescription as will enable any one skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, forming part of this specification.

My invention relates to a coupler release rigging and particularly tothat type of rigging in which a rotary actuating rod is rovided with anoperating arm passing directly through the lock pin eye. It is essentialthat the operating arm and lock pin have relative movement bothlaterally and longitudinally in a horizontal plane. Relative movement inone direction, either lateral or longitudinal, is secured by themovement of the arm through the eye.

The object of my invention is to provide for relative movement of theparts in the second direction and this I secure by providing a memberattachable to the lock pin and having formed therein an auxiliaryelongated eye either parallel with or at right angles to eye of the lockpin as the case may require.

In the accompanying drawings which illustrate release rigging made inaccordance with my invention, Figure 1 is a top plan view of a railwaycar to which is applied a member having an auxiliary eye elongated inthe direction of the length of the car. Figure 2 is an enlarged end viewof the member provided with the auxiliary eye, together with theadjacent parts. Figure 3 is a view taken at right angles to Figure 2.Figure 4 is a view similar to Figure 1 but showing a member providedwith an auxiliary eye elongated in a transverse direction. Figure 5 isan enlarged side view of the eye carrying member shown in Figure 4.Figure 6 is a view taken at right angles to Figure 5, and Figure 7 is aside view of the parts shown in Figure 1.

10 indicates a railway car provided with a coupler head 11 of the usualvertical plane type. The coupler head 11 has a lock pin 12 in which isformed a transverse eye 13. 14 is the actuating rod rotatably mounted inbrackets 18 secured to the end of the car 10. Projecting forwardly fromthe inner end of the rod 14 is the operating arm 15 which may passdirectly through the eye of the attachable member or may be providedwith an extension 16 projecting in a transverse direction. In eithercase the arm preferably terminates in a hook 17 The actuating rod 14 iscontrolled by a handle 19 which is pivoted at 20 to a bent over portionof the outer end of the rod 14 so that it may drop back into verticalposition, after the pin is lifted, independently of the movement of thesaid rod.

Referring first to Figures 1, 2, 3 and 7, a housing 21 is provided,fitting snugly over the upper end of the lock pin 12 and held inposition by a headed stud 22 passing through suitable openings in thehousing and through the eye 13 of the look pin. The stud 22 may beretained by any suitable means, such for example, as the cotter pin 23.The housing 21 is provided with an auxiliary eye 24 extending in alongitudinal direction to compensate for the longitudinal movement ofthe coupler head, the lateral movement being compensated for by themovement of the extension 16 through the eye.

In Figures 4 5 and 6 I have shown a modification in which the extension16 is omitted. In this construction, the longitudinally extendingauxiliary eye 24 is replaced by an eye 25 elongated in a transversedirection. It will be evident that this construction will secure thesame results as that first described. The function of the parts arehowever, reversed, the movement of the rod through the eye compensatingfor the longitudinal movement of the coupler while the elongation of theeye compensates for the lateral movement thereof.

Having fully described my invention, what I claim; asnew and desire tosecure by Letters Patent of the United States is:

1. In a device of the class described, the combination, with a verticalplane coupler provided with a lock pin, of a shaft therefor mounted. forrocking movement only and having an operating arm, and a housing adaptedto fit over the upper end of said lock pin, said housing being providedwith an elongated auxiliary eye through which said arm passes.

2. In a device of the class described, the through the pin eye, and anauxiliary eye combination, With a vertical plane coupler, carried bysaid housing and through which provided With a lock pin, of a shafttherefor said arm passes. 10 mounted for rocking movement only and Intestimony whereof, I have hereunto 5 having an operating arm, a housingadaptset my hand and aflixed my seal.

ed to fit over the upper end of said pin, fastening means for saidhousing passing STERLING CAMPBELL [L.s.]
